Summary: A base-catalyzed one pot reaction has been developed for the synthesis of 2-(1H-indol-3-yl)- acetamides via coupling of 1,1-carbonyldiimidazole with 2-(1H-indol-3-yl) acetic acid resulting in the formation of a reactive intermediate which on treatment with different substituted anilines afford 2-(1H- indol-3-yl)-acetamides in good yield.
